<p><span class="user-mention" data-user-id="116009">@nikomatsakis</span> in your talk, at some point <a href="https://youtu.be/_agDeiWek8w?list=PLgC1L0fKd7UkVwjVlOySfMnn80Qs5TOLb&amp;t=1869" target="_blank" title="https://youtu.be/_agDeiWek8w?list=PLgC1L0fKd7UkVwjVlOySfMnn80Qs5TOLb&amp;t=1869">you mention</a> that you have some examples more complicated than "problem case <a href="https://github.com/rust-lang/rust/issues/3" target="_blank" title="https://github.com/rust-lang/rust/issues/3">#3</a>" that even the (computationally infeasible) stronger NLL couldnt handle, but polonius can. Could you point me to such an example?</p>
